PETER PERDOMO FIGUEROA, OF 1\TE\V YORK, N. Y.

GAS-IGNITER.

Application filed January 26, 1915.

To all whom 272? may concern Be it known that I, PETER PERDOMO FIG- UEROA, a citizen of the United States, and

.resident of New York in'the count of New 7 York and State of New York, have invented certain new and useful Improvements in Gas-Igniters, of which the following is a specification.

This invention relates to gas igniters and especially to devices to be secured to gas burners and its object is to provide sparks from a pyrophoric alloy by means of a serrated wheel working on the same and operated by a cord or chain passing around a pulley on the axle of the serrated wheel, as will be more fully described in the following specification, set forth in the claims and illustrated in the accompanying drawings, wherein,

Figure l is a side elevation of a simple form of the device. Fig. 2 is a sectional view of the same. Fig. 3 is a side elevation of a modified form. Fig. a is a front view of the same. Fig. 5 is another modification of the igniter. Figs. 6, 7 and 8 show modified means for attaching the device to the burner. Fig. 9 shows the lighter applied to an incandescent burner. Figs. 10 and 11, are views of details. Fig. 12 illustrates an automatic action. Fig. 13 shows how the device may be applied to a gas stove. Fig. 1% is a plan view of a gas stove showing a modified form of the igniter applied thereto. Fig. is a cross sectional view of the same.

When the gas cock is turned on in a bracket to release the gas for the burner and igniting means are necessary, a sparking device is provided in the present invention, which is sufficiently remote from the flame to escape damage therefrom, yet capable of furnishing the necessary igniting sparks by the quick rotation of a roughened wheel on a block of pyrophoric material.

In carrying out this invention a bracket 10 is provided with a ring 11 to fit over the nipple 12, on which the burner 13 is secured and screwed down so tight that the ring and bracket are firmly secured, and at the outer end of the bracket is a tube 14 carrying the sparking piece 15 in its lower end and which is pressed down by the spring 16 and adjusting screw 16. In the fork of the bracket is journaled the friction wheel 17 and on its shaft is a sprocket wheel 18 carrying a chain 19 that engages the teeth of the Wheel. This chain may be of any type, or

it may be of cord or wire, and is an endless band adapted to pass over and down one side of the sprocket wheel, so that when it is seized by the hand of the operator and pulled downward sharply, the friction wheel 17 which is carried bythe same shaft as the sprocket, is rotated rapidly against the pyrophoric block 15 and sparks caused to fly on a tangent toward the escaping gas of the burner.

The chain 19 may be of any desired length to permit of the above described movement and the wheel flanged about the sprocket teeth, as shown in Figs. 1 and 5, to retain the chain and keep it from slipping. In case that the chain is pulled to ignite the gas, there is little danger of its being carried to an extreme or beyond its length and consequently wrecking the device or breaking any of its delicate parts, as is liable to occur if the chain is positively attached to some part of the device.

In Figs. 3, 4 and 5 are shown somewhat more compact and substantial constructions and yet sufliciently remote from the flame to escape damage, and consisting of the tubular upright 20 with bearing yoke 21 carrying the shaft 22 for the friction and sprocket wheels. The upright contains the pyrophoric block 23 which is pushed upward against the friction wheel by a spring 24: whose pressure is regulated by the screw 25. Fig. 5 shows the shaft 22 provided with a return spring 26 and when the chain 19 is pulled down in the direction of the arrow and released, the tension put upon the spring causes it to quickly rotate the friction wheel and send the sparks in the direction of the burner. A. somewhat similar construction is illustrated in Fig. 12 where the two wheels are loosely mounted on the shaft 2'7 and the sprocket wheel 28 adapted to rotate and shift laterally also. A stud 29 on the sprocket wheel engages a projection 30 on the-friction wheel, when prop erly positioned, and partly rotates the friction wheel 31 until the cam 32 permits of a right hand shift of the sprocket in consequence of the pressure of the spring 33 and causes the disengagement of the stud and projection, releasing the friction wheel. The rotation of the latter in the first instance has put the spring 34 under tension and the wheel 31 on being released flies back rapidly and its friction produces the sparks from the pyrophoric block 35.

Fig. 10 shows the construction of the sprocket wheel where an ordinary linlr chain is used, the teeth are saw-shaped so that the chain will'engage them when moving in one direction only, but will slide over them on the reverse movement. Fig. 11

shows a similar arrangement of teeth for a.

V and at the same time to increase the speed of the friction wheel.

The igniter may also be applied to a gas stove as shown in Fig. 13, by securing the friction wheel and pyrophorio block to one of the pipes supplying the burner 46 and connecting the band 47 with them through suitable gearing, as described in the above. Toward the front of thestovea pulley 48 is secured and over which the band passes so that it is accesssible to the operator, who pulls down on it and rapidly rotates the friction wheel.

It is obvious that other applications of a band-chain may be resorted to without departing from the essential features of the invention, as above described, or the scope of the appended claims.

As illustrated in. the views of the gasstove in Figs. 14 and 15, the igniter of Fig. 12 is applied thereto and the band 49 operates the wheel 28 with the friction wheel on its shaft The tube 50 is secured to the pipe 51 of the burner 52 and carries'a sprocket wheel 53 around which passes the endless chain 49 to drive the wheel 28. A crank arm 54 is secured to the wheel 53 and a similar arm 55 is secured to the lower end of the valve plug 56, connected by a link 57 and thereby caused to work in unison when the handle 58 of the valve isturned to admit the gas to the burner. The chain turns the wheel 28 and the friction wheel until the connection is removed and the friction wheel returningcreates the igniting sparks. This arrangement permits the turning on of the gas and the rotation of the friction wheel after the gas is released. 7

What I claim is: r

1. In a gas igniter, the combination with a pyrophoric block secured to a gas burner, of a friction wheel impinging the block, aratchet wheel connected with the friction wheel, and a chain on the ratchet wheel adapted to operate the wheel in one direction and slip whenpulled in the other direction.

In a gas igniter, the combination with a pyrophoric block secured adjacent the burner, of a friction wheel impinging on the block and journaled in a bracket carried by the burner, a ratchet wheel on the shaft of the friction wheel and having saw teeth, and an endless chain on the ratchet wheel and adapted to act on the teeth when pulled in one direction and slide over them when reversed.
